6-14 Inertia Ratio Switching Function

6-14-1 Outline of the Function

You can switch between the inertia ratio 1 and 2 using Inertia Ratio Switching Input (JSEL). This
function is effective if it is used when the load inertia changes in 2 levels.
You can use the inertia ratio switching function in the following situations.
• The servo is ON.
• The Servomotor can rotate normally without any failures.
• The realtime autotuning function is disabled.
• The adaptive filter function is disabled.
• The instantaneous speed observer function is disabled.
• The disturbance observer function is disabled.

Precautions for Correct Use Precautions for Correct Use
• Be sure to switch the inertia ratio with the Servomotor stopped.
• Vibration may occur even when the Servomotor is stopped if the values set in Inertia Ratio 1
and Inertia Ratio 2 differ significantly. Before using the Servomotor, check to be sure that the
vibration causes no problem.
